It's been a long, hard day. It's been especially challenging because Spock is on a ship full of illogical humans. When his work is done, Spock knows how to take care of himself. He puts on some soft jazz, takes off his boots and slips into his giant pile of tribbles.

The tribbles are responsive. They trill softly, rhythmically, like a white noise machine. Sleep comes easily to Spock in this painting by Cameron Kobe.
